Filed: 1982-10-25
Abstract: PURPOSE:To supply stable source potential with no influence affected by the variation of a process with simple constitution by forming a common source potential setting circuit for a non-volatile memory cell array by a diode and a switching MOS transistor (TR). CONSTITUTION:The common source potential setting circuit for the non-volatile memory cell array 10 is formed by p-n junction diode 21 and a MOS switching TR22 connected to the diode 21 in parallel, and at the reading mode, the TR22 is on and the common source potential is set up to almost the earth potential. At the writing mode, the TR22 is turned off and the built-in potential of the diode 21 is turned to the setting potential of the common source, a fixed potential with high controlling property based upon the characteristics of the diode 21, so that a non-selective cell is prevented from current leakage. Consequently, the stable source potential can be supplied with no influence affected by the variation of the process with the simple constitution.

Title: Extinguishing method of kerosene burner
Inventor: FURUMOTO MICHITAKE
IPC: A62C3/00
Filed: 1982-10-27
Abstract: PURPOSE:To eliminate the generation of bad smell when a burner is turned off by a method wherein gaseous fuel is supplied to a burner nearly at the same time as kerosene is stopped to supply to the burner so as to bring to extinguish the kerosene by burning the kerosene vapor in the burner and said gaseous fuel in order to completely burn the kerosene vapor by making up for the lean state of mixture produced by the decrease of kerosene vapor by the gaseous fuel. CONSTITUTION:When an operating switch 13 is pivoted to the fire-extinguishing position to turn off a burner, the tip of an arm 15 strikes against the top surface of an auxiliary lever 38 pivotally supported by a pin 37 at the tip of a second lever 20 in order to pivot clockwise a control lever body 17 about a fulcrum shaft 16. Consequently, a transmission lever 21 pushes up a valve spindle 27, resulting in opening a gas on-off valve 10 so as to supply gaseous guel to a burner 8. On the other hand, a kerosene on- off valve 6 is closed by the return motion of the operating switch 13 to a stop position. Accordingly, a small amount of the gaseous fuel is supplied to the burner 8 nearly at the same time as the stoppage of supply of kerosene to the burner 8, resulting in completely burning the kerosene vapor and extinguishing it by making up for the generation of lean mixture of air and kerosene with the decrease of kerosene vapor in the interior of the burner 8 by the gaseous fuel.
